问题
For the below paragraph, I am going to paste it into Notepad++ and use the Count functionality to find the count of "test of foo bar.\r\nThis is a" I know I can do this using the "Extended" Search mode but my real life scenario requires regex.
test of reg ex
This is a test of foo bar
This is a test foo
This is a test of foo bar
This is a test foo
This is a test of foo bar
This is a test foo
In plain English, I am trying to
- Find location of "This is a"
- Back track and stop at the first instance of the word test.
I am not too sure how to word the title, I'll modify it later
How about this? with random a1-f3 texts
test of d1
test of e2
test of f3
This is a test of a1
This is a test foo.
This is a test of b2
This is a test foo.
This is a test of c3
This is a test foo.
Also would like to use the s modifier since notepad++'s . matches newline uses the s modifier. I almost have what I need in the below screen cap except for the first match, it matches too much.

What I have now, which over matches

Try this regex:
test of .{2}\s+This is a
Don't forget to uncheck the option . matches newline. (Alt + .)
Tested on Notepad 6.7.8.2

By your definition, shouldn't more text be selected, like this:
test of d1
test of e2
test of f3
This is a test of a1
This is a test foo.
This is a test of b2
This is a test foo.
This is a test of c3
This is a test foo.
But anyways, since you're only counting, you can use this:
.test of.*?\nThis is a
to match what you wanted (including one character before the word test since it seems like you don't want any 'test' that begin a line
test of d1
test of e2
test of f3
This is a test of a1
This is a test foo.
This is a test of b2
This is a test foo.
This is a test of c3
This is a test foo.
EDIT: Not using '.':
test of(\S|\s)*?This is a
